Patent DE-4118829-A1 (DE)
Title: Stopping slubbing feed mechanism to spinner work station - involves bringing electromotor to rest through event registered by sensor which is electronically evaluated, etc.
Inventor: WALTER WOLFGANG DIPL ING
IPC: D01H1/244
Filed: 1991-06-07
Abstract: The slubbing feed mechanism to the workstation of a spinner, esp. a ring spinner with separate electro-motor drives for each spindle, is stopped (7) when the electro-motor (1) is brought to rest through an event registered by a sensor which is electronically evaluated (4) as necessary to stop the spindle drive. While the motor (1) is brought to rest, at least one of the coils (W1-W3) provides induced electrical energy for an electro-mechanical converter (6) to activate the slubbing stop mechanism (7). The event requiring a motor (1) stoppage is detected through an induced voltage at a sensor coil, or an induced voltage through evaluation of the total voltage of the separate coils (W1-W3) while the motor (1) is operating and the voltage at the unseparated coils. The event is a change in the frequency or phase of the voltage being assessed. The induced voltage is rectified at least at one coil of the electro-motor and the generated DC is used to control an electro-magnet. When the slubbing stop (7) has been activated, after a motor stoppage, it remains automatically in the activated setting. ADVANTAGE - The system provides the required electrical energy to activate a slubbing stop mechanism at a given workstation, without wiring through the whole spinning assembly to power the electro-mechanical converters.

Patent DE-4136833-A1 (DE)
Inventor: SCHUEERS ANDREAS DR
IPC: B60K15/077
Filed: 1991-11-08
Abstract: The fuel pressure in a fuel line (5) leading to an internal combustion engine (3) is customarily regulated in such a way that a pressure regulator (9) diverts a partial flow into a return line (11) opening without pressure into a fuel tank (4). The branch line (10) and the pressure regulator (9) are customarily arranged near the internal combustion engine (3) in a closed engine compartment (2), e.g. of a motor vehicle (1). This, however, causes both the fuel flow through the return line (11) and the fuel in the tank (4) to be heated by the heat given off by the engine. To prevent this it is proposed to arrange the branch line (10) and the pressure regulator (9) outside the engine compartment (2) near the fuel tank (4). It is also proposed to fit a reversing valve (14) and a scavenging line (15) in order to supply the injection manifold (6) with the full flow of fuel conveyed by the pump after the engine has been started.

Title: Surface prepn. of plastic profiles for use with hot-melt adhesive - by irradiating with pulsed short wavelength radiation, esp. 320-440 nm UV, to form surface micro-cavities to allow penetration of adhesive
Inventor: BARBERAN JESUS
IPC: B29C59/16
Filed: 1992-08-24
Abstract: A process for the surface prepn. of plastic profiles (I) in order to improve their adhesiveness when using hot-melt adhesives comprises irradiating the surface with a pulsed beam of radiation of very low wavelength (L), resulting in cleavage of the mol. structure at the surface without penetrating inside the substrate, and leaving microscopic cavitites into which the adhesive can penetrate. Pref. radiation is very low wavelength UV, esp. with L = 320-440 nm. The pref. substrate is a profile of rigid PVC, methacrylate, plastic or similar material; this is irradiated as above, covered with a layer of paper, wood, PVC or PVC/paper which is coated with hot-melt adhesive, and then passed over a suitable hot roller to bond the coating to the substrate. USE/ADVANTAGE - Used, e.g. for applying decorative coatings of paper, plastic, wood, etc. to plastic substrates such as walls, doors, ceilings, windows, furniture parts etc. The process provides the surface of the substrate (acrylic resin, polyamide, PE, PP, polyurethane, PVC etc.) with the necessary porosity to ensure adequate penetration of hot-melt adhesive, without adversely affecting the bulk properties of the substrate. The process ensures high bond strength using low-cost hot-melt adhesives which can be applied in the open air (contrast solvent-contg. polyurethane adhesives).

Patent DE-4234772-A1 (DE)
Inventor: OHMS FRANZ DIPL ING
IPC: H02M3/337
Filed: 1992-10-15
Abstract: In a voltage converter for switching operations, such as a push-pull voltage converter (GW), the switching-on pulses for the switching members (S1, S2) during a switching-on operation have different lengths, in such a way that the average value of the absorbed energy current does not exceed a predetermined limit value. On the contrary of usual processes, the switching-on pulses are not regulated, but the different switching-on times in several dividing phases are fixed in advance depending on the inductivity (LS) of the direct voltage converter (GW). This process ensures that the average value of the switching-on current does not substantially exceed a predetermined nominal value. This is particularly advantageous for the energy supply to travelling-wave tube amplifiers.
